Esbuild

CI

Mix tasks for installing and invoking esbuild.

Installation

If you are going to build assets in production, then you add esbuild as dependency on all environments but only start it in dev:

def deps do
  [
    {:esbuild, "~> 0.1", runtime: Mix.env() == :dev}
  ]
end

However, if your assets are precompiled during development, then it only needs to be a dev dependency:

def deps do
  [
    {:esbuild, "~> 0.1", only: :dev}
  ]
end

Once installed, change your config/config.exs to pick your esbuild version of choice:

config :esbuild, version: "0.12.15"

Now you can install esbuild by running:

$ mix esbuild.install

And invoke esbuild with:

$ mix esbuild default assets/js/app.js --bundle --minify --target=es2016 --outdir=priv/static/assets/

The executable is kept at _build/esbuild.

Profiles

The first argument to esbuild is the execution profile. You can define multiple execution profiles with the current directory, the OS enviroment, and default arguments to the esbuild task:

config :esbuild,
  version: "0.12.15",
  default: [
    args: ~w(js/app.js --bundle --target=es2016 --outdir=../priv/static/assets),
    cd: Path.expand("../assets", __DIR__),
    env: %{"NODE_PATH" => Path.expand("../deps", __DIR__)}
  ]

When mix esbuild default is invoked, the task arguments will be appended to the ones configured above.
